Biweekly 

1. Occurring twice per week (this is true no matter what Dan or his English professor mom says. My mom was a book editor and she looked it up in the dictionary. I don't care that she originally thought it was definition #2. She found it in Merriam Webster, the dictionary Dan recommended).

2. (Occ.) Every two weeks.

The College of William and Mary's Flat Hat newspaper is published biweekly, allowing me to read it twice every week.

Because biweekly first and foremost means twice per week, I do not owe Dan any money.

Andrew: "Yeah, didn't you know, Dave's biweekly."

biweeksly 

Biweeksly (adjective): Used to indicate that something occurs once every two weeks, as opposed to biweekly, which indicates that something occurs twice in one week. (This helps to resolve the issue of the otherwise ambiguous usage of the word biweekly.)

Person A: So the event is held biweeksly.
Person B: You mean biweekly?
Person A: No, the s is on purpose, it's supposed to indicate a plural of weeks, as in this event is held once every two weeks.
Person B: Oh! That's great! Because otherwise I was just going to have to ask you to clarify what you meant by biweekly!
